Four thousand, five hundred. In decimal notation, 4,500 metres equal 4.5 km.
A quarter note is worth half the duration of a half note in music notation.
A half note receives two beats in music notation.
"Half a trillion" or 500 billion would be written exponentially 5 x 10^11 (5 times 10 to the 11th power).On the US "short scale" the value 1 trillion is 1,000,000,000,000 and the scientific notation is 1 x 10^12.(10 to the twelfth power)
29,500,000 is twenty-nine million five hundred thousand, or twenty-nine and a half million. Or, 2.95 x 107 in scientific notation.
Half of five iS 2.5
A quantity is said to be subject to exponential decay if it decreases at a rate proportional to its value. The time required for the decaying quantity to fall to one half of its initial value.Radioactive decay is a good example where the half life is constant over the entire decay time.In non-exponential decay, half life is not constant.
4 is not one half of five. 2.5 is one half of five.
Ionic Method or Half Shell Notation.... the symbol is shown and the electrons are distributed on the different energy levels represented by half-shell
8.5 in Scientific Notation = 8.5 x 100
For an exponential function: General equation of exponential decay is A(t)=A0e^-at The definition of a half-life is A(t)/A0=0.5, therefore: 0.5 = e^-at ln(0.5)=-at t= -ln(0.5)/a For exponential growth: A(t)=A0e^at Find out an expression to relate A(t) and A0 and you solve as above
5 in a half? five and a half five and a half what?
